Pretty much on the money Steve, & just to add to this thread, on the main valve the vent tube extends into the bottle the appropriate distance so if the correct procedure for filling is followed you can only fill it to the 80/85% capacity, also the correct procedure for selling gas when you refill at the local camping store should be by weight... How many times have we had a bit left in the bottle, even 1/4 full... Too bad you still pay full price for that size cyl. And as well also!!!! Saw in the paper the other day some plonker going on about the differences between LPG Auto & LPG Domestic... All doom & gloom if you used in the opposite application!!!!! I think that one was put to rest in this forum some time back... A bloke wrote in to say he had a bro in law or some really who drove an LPG tanker, did fill ups at servos local fish & chippery, any old bulk LPG cyl on the run. And while I`m here another point to go with the first post Re capcity, I`ve been running LPG for a good while now & have found that if tank is compleatly empty I can get more in than the rated capasityof the tank at least 15 lts the efficency of the delivery pump has a big bearing on this factor. Thats my fripence worth. Cheers Tommy.

Having spent 40 years in the LPG industry both on the tools and in marketing let me say there is a huge difference between auto gas and camping cylinder gas. Auto is a mix of Propane and Butane up to 50/50 and camping cylinder gas is straight Propane.
The difference being that Propane boils at -44% c and Butane boils at 0%c (that is tuns from a liquid to a gas)
About the doom and gloom Tommy if you are asked to attend a Caravan one morning where a auto gas filled cylinder has been left on supplying the stove and gone out because the Butane in the cylinder would not vapourise (turn to gas) but then filled the van and put the occupants to sleep permanently you would be careful.

T.D. perhaps you could post a direct link about the gas killing the caravan occupants but I'm prepared to call it an urban myth.
The aromatics introduced during the gas production are unmistakable and the smallest amount would alert the occupants, volumes enough to kill would set alarm bells going in anyones mind well before it reached such levels.

TD I`m sure you`re credentials are A1 & I have no reason to disbelieve when you say there is a huge difference between domestic & auto LPG... What puzzles me though is why a bloke would come on here some time back during a debate about this very subject & say his bro in law or what ever relly it was drove the LPG tanker filling up domestic & servo LPG tanks.
A place I worked at yrs ago had Acco transit mixers on LPG, the resident fitter would regularly fill his & everyone elses domestic cyl from the auto gas with no apparent problems, plus the story about the couple in the van sounds a bit dodgy????? Why would they both go to sleep right in the middle of cooking something?????? All to much for this supreme sceptic. Cheers Tommy.
